There are a lot of fine Lightboxes on the market, both free and commercials, but they all need to be installed into Your Confluence:
All of the stuff below is quite generic and samples only
Under Confluence
Download the lightbox zip, upload it to the server and place the files under the install:
cd /opt/confluence/confluence mkdir mylightbox cd mylightbox mv ~/mylightbox.zip . unzip mylightbox.zip
Somewhere else in the filesystem
Download the lightbox zip, upload it to the server and place the files under the install:
This requires support for Linking in Tomcat
cd /data mkdir mylightbox cd mylightbox mv ~/mylightbox.zip . unzip mylightbox.zip ln -s /data/mylightbox /opt/confluence/confluence/mylightbox
The Common Part
Now these can be referenced as /opt/confluence/confluence id the server root, so in Custom HTML add:
<!-- MyLignbox --> <link rel="stylesheet" href="/mylightbox/css/mylightbox.css" type="text/css" media="screen" charset="utf-8" /> <script src="/mylightbox/js/jquery.mylightbox.js" type="text/javascript" charset="utf-8"></script>
Some lighboxes requires to be initiated ($ is AJS.$ for Confluence):
<script type="text/javascript" charset="utf-8">
AJS.$(document).ready(function(){
AjS.$("a[rel^='mylightbox']").mylightbox();
});
</script>
